Hiv infection is caused by a retrovirus....This retrovirus binds to CD4 cells (for the most part). You may detect the virus by several different methods. An elisa test (enzyme linked immunosorbent assay). You may also detect it by doing a test referred to as a western blot (a gel protein electrophoresis). Thirdly by pcr (polymerase chain reaction) which actually detects individual viruses.

Antibody test HIV:
It is a test for the two main types of HIVantibody (ab), types 1 and 2. Eia is the primary test method that is inexpensive, but it occasionally has false positive result, so there is a reflex test (automatic confirmation test) using a more expensive but more trustworthy test (immunoblot) to make very sure that the eia test result really is positive. There is a pcr test to detect HIV itself.

Yes and no:
Usually people tested within the first 3-6 weeks of an exposure can have a false negative, but 65 days out should be enough time to have a positive test, so if it was negative, it's very likely it is correct. That said, if you have had a repeat exposure you are concerned about, you would need to be retested.

Viral Testing:
To test for many infections we look for antibodies (your body's reaction to something new or foreign). In the case of HIV infection these antibodies can take three to six months to be positive on a test. This old fashioned test is a reliable and common screening tool. But, it is not the best test if one is possibly exposed. We now send HIV genetic tests which can be positive by day 21 post expos.

Nucleic acid test:
Negative result on EIA is good but not the final word. You may get a HIV nucleic acid test and if that is negative at 6-8 weeks, you are in the clear. EIA needs to be repeated, as rarely, it may take up to a year to become positive.

It depends:
In a situation like this you have one positive test and one negative test. The lab should run a tie-breaker test (HIVRNA) to give you a real answer. Also, the first test may be an older test 2nd or 3rd generation) instead of the latest 4th generation) test. It also depends on if you have flu-Like symptoms. Seek help from a specialist in HIV who can help you understand.
